Having a third, and even a fourth, argument need not
be difficult and would certainly be useful, especially
(in my direct experience) in teaching beginners tacit
programming.
At the risk of boring long-term readers of this forum,
my repeated suggestion has been for the use of [. and
]. to name operands just as [ and ] name arguments.
Then with &[. [.& &]. or ].& you would effectively
have third an fourth arguments. There would be many
other simplifications then made available as well.

Great phrase ! I'll borrow it some time if you don't
mind.
